TD1482A PR from Techcode Semicon, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BS | passive | High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-channel MOSFET switch. Connect a 0.01μF or greater bootstrap capacitor from SW to BS to power the high-side switch. Absolute max: VSW − 0.3V to VSW + 6V. |
| 2 | IN | power_in | Supply Voltage input. The TD1482A operates from a +4.75V to +20V unregulated input. An input decoupling capacitor (C1) is required to prevent large voltage spikes at the input. |
| 3 | SW | power_out | Power Switching Output. SW is the switching node that supplies power to the output. Connect the output LC filter from SW to the output load. A bootstrap capacitor is required from SW to BS to power the high-side switch. Absolute max: 20V. |
| 4 | GND | power_in | Ground return for the device. |
| 5 | FB | input | Feedback Input. FB senses the output voltage to regulate that voltage via a resistive voltage divider from the output. The feedback threshold is 0.923V (typ). Overvoltage protection triggers at ~1.1V. |
| 6 | COMP | output | Compensation Node. COMP is used to compensate the regulation control loop. Connect a series RC network from COMP to GND to compensate the regulation loop. In some cases, an additional capacitor from COMP to GND is required. |
| 7 | EN | input | Enable Input. Digital input that turns the regulator on or off. Drive EN high to turn on the regulator, drive it low to turn it off. Pull up with a 100kΩ resistor for automatic startup. Enable threshold ~1.5V (typ), lockout threshold ~2.5V (typ). |
| 8 | SS | passive | Soft-Start Control Input. SS controls the soft-start period. Connect a capacitor from SS to GND to set the soft-start period; a 0.1μF capacitor sets the soft-start period to 15ms. Soft-start charging current is ~6μA. Leave unconnected to disable the soft-start feature. |
